Can trained canines be trusted to give evidence in court?  

Its a strange case here in India. A man murdered a child and buried it under stones. When the body was discovered, it became difficult to even identify the body. A trained police dog was then brought, sniffed and took the police to the house of a man. Based on this the police arrested him. The matter went to court. The lower court declined to accept the verdit of the dog. The matter is now with the High Court in appeal against the ruling of the Small Court. We are all egerly awaiting the judgement. What are your views on this.?
